During the 2018 World Cup, we heard a lot about the technology used, especially Video Assistant Referee (VAR). In the last game, Sweden beat South Korea thanks to the help of these technologies.

VAR basically supports the work of the referee and his assistant in the field. They can review events in seconds, as they have access to some reruns from different angles.

The use of VAR at the 2018 World Cup was initiated by British audio-visual suppliers Crescent Comms and computer systems used in various sports called Hawk-Eye. VAR has access to 33 cameras, including eight super slow motion cameras and four ultra-slow motion cameras, as well as two additional offside cameras.

In Russia, VAR officials will lead from the Video Operation Room (VOR) located at the International Broadcast Center (IBC) in Moscow. VOR is located at the center, so the VAR team for all 64 matches will sit on the IBC.

The team consists of video assistant referees (VARs) and three assistants (AVAR1, AVAR2, and AVAR3). All FIFA member official video assistant referees.

The FIFA Referee Committee has selected 13 Referees, who will act as assistant video assistants during the 2018 FIFA World Cup Russia which has previously been selected from his experience.

VAR will see the main camera on the top monitor and check or review incidents on the four divided monitors. He is responsible for leading the VAR team and communicating with the referee.

AVAR1 concentrates on the main camera and makes VAR informed about the live game if the incident is being checked or reviewed.

AVAR3 focuses on TV program feeds, helps VARs in evaluating incidents and ensures good communication between VAR and AVAR2 located at offside stations.

AVAR2 is an assistant referee located at an offside station. He anticipates and examines any potential offside situations to expedite the VAR review and review process.
